Richard Crane (
http://www.imdb.com/name/nm0186415) veteran serial player, heads up this "D" list cast for fun and frolic in outer space. Sally Mansfield is quite young, stunning in her "cross your heart bra" space outfit and amazingly liberated for the era, frequently asserting that girls *do* belong in rocket ships.
If you are familiar with the famous ending from "North by Northwest" you might enjoy the last few moments of part one. Rocky argues that women don't belong in space but Winky replies "she's going to come in mighty handy…" just as we cut to an exterior shot of the Orbit Jet fully inserting itself into the space station "landing tube." Hmmm… might handy indeed…
